Laeuter, K.S. Lee, K.H. Jung, R.K. Vatsa, J.P. Mittal, H.-R. Volpp Title: Absolute primary H atom quantum yield measurements in the 193.3 and 121.6 nm photodissociation of acetylene Journal/Source: Chemical Physics Letters, 358, 314–319, (2002) Data: (diagram, table, disk): Energy/Wavelength range: 193.3 nm; 121.6 nm Resolution: Temperature: Temperature dependence: Pressure: Comments: Using HCl and CH4 photolysis at 193.3 and 121.6 nm, respectively, as a reference, values of PHI(193.3 nm) = 0.94 +- 0.12 and PHI(121.6 nm) = 1.04 +- 0.16 were obtained.
